The whole Intel HDMI Laptop thing I don't think I would have ever seen
if not using the HDMI connected to a smart tv, but I put the blame on
the Intel system because the kernel activity continue even while HDMI is
not in use. Apparently there is some controversy over intel driver e1000
or using e1000e noted by both lwn.net and Linus, apparently e1000e is
used even when not needed or wanted.
